What two numbers multiply to -312 and add up to 311?

Here we answer the question: "What two numbers multiply to -312 and add up to 311?"

The answer to your question is:

-1 and 312

Below we illustrate and prove that -1 and 312 multiply to -312 and add up to 311:

-1 × 312 = -312
-1 + 312 = 311

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 311x - 312 = 0

If so, the solution to factor the quadratic equation above is:

(x - 1 ) (x + 312)

To summarize, since -1 and 312 multiply to -312 and add up 311, you know that the following is true:

x² + 311x - 312 = (x - 1 ) (x + 312)
